---|---|---|---|---|---|
32 | c. 1871 | ?????? | Lister Limb microscope sharing features of more than one known model with a stage virtually identical to those found on major microscopes by Pike. Probably dates to before October 1871. | This collection | |
52 | c. 1873 | SECTOR | No surviving example of this stand is known to the author. | Reported in the JRMS of 1880 to have first been 'exhibited' in 1873. | |
77 | c. 1873 | 'A' | This example was sold in the 20th century by Tesseract in 1986. It was in poor condition and lacked its substage assembly. It had the important signature of 'W. H. Bulloch Maker, T.F. Nelson, Agent, Chicago' | ||
87 | c. 1876 | 'C' | This example was sold in 1876. | Collection of Allan Wissner | |
103 | c. 1878 | 'D' | Note the 'English' or 'Crouch' type of foot, rarely if ever produced by other American microscope makers. | Private Collection | |
104 | c. 1880's-1890 | 'Histological' | Signed 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880'. This stand is unusual in that it has a Meyrowitz signature but straight rack and pinion which may make it earlier than the other Meyrowitz-signed stands. | Private Collection | |
112 | c. 1891 | HISTOLOGICAL | Note the single swinging tailpiece which carries both the condenser assembly and the mirror, and the flat tripod foot. It is signed: 'BULLOCH'S PATENT, E. B. Meyrowitz, MAKER, NEW YORK, PAT'D 1880' although the '1880' looks to be crudely added, and would be incorrect on any account, as there is no Bulloch patent in 1880 for a microscope, as it was in 1879. | Private Collection | |
115 | c 1880 | CONGRESS | Note the new form of glide stage with two supporting pressure points instead of one. | Private Collection | |
117 | c 1880 | NEW BIOLOGICAL (BIOLOGICAL No.1) | This example has stage rotation but not a mechanical stage. The foot is signed: 'W.H> BULLOCH, CHICAGO, PAT'D 1879' This, unlike the next No. 117, is a purely Bulloch product. This is the lowest serial number for this model I know of at the time of this writing(2017) |
Private Collection | |
117 | c. 1891 | HISTOLOGICAL | Note that this microscope has a single swinging tailpiece which carries both the condenser assembly and the mirror, and the asymmetrical flat tripod foot. The foot is signed 'Bulloch's Patent, E.B. Meyrowitz Maker, New York, Pat'D 1879'. This example has a glass-covered glide stage ('Sliding Object Carrier'), with single pressure point, but the slide carrier is missing. The word 'maker' associated with Meyrowitz's signature implies this stand was made after Bulloch's death, about 1891, but might also simply be a Meyrowitz claim tolerated by Bulloch at the time. | Private Collection; sold at Christies auction in Los Angeles in October of 2001. | |
121 | c 1880 | NEW BIOLOGICAL (LATER CALLED THE BIOLOGICAL NO. 1) | Note the second version of the Bulloch Mechanical stage with concentric horizontal controls projecting from the top of the stage. This model could be supplied with either a 'Clip Stage' (plain stage with stage clips), a mechanical Stage, or 'Sliding Object Carrier' Stage; it could also be supplied with Gillett diaphragm, as well as graduated substage and mirror bars, and even as a binocular model for extra cost. | Private Collection | |
129 | c 1880 | NEW BIOLOGICAL (LATER CALLED THE BIOLOGICAL NO. 1) | This model was supplied with a 'Sliding Object Carrier' Stage; it could also be supplied with Gillett diaphragm, as well as graduated substage and mirror bars, and even as a binocular model for extra cost. It is signed W.H.BULLOCH, CHICAGO, PAT'D 1879, 129 | Microscope Collection of Science Museum, London | |
132 | c 1880-1882 | PROFESSIONAL | Note the first version of the Bulloch mechanical stage with concentric horizontal controls projecting from the bottom of the stage. By number 138 this had changed (see below). | Private Collection | |
138 | c 1880-1882 | PROFESSIONAL | Note the second version of the Bulloch Mechanical stage with concentric horizontal controls projecting from the top of the stage. | This Collection | |
139 | c 1880-82 | LITHOLOGICAL (first form) | According to a review article published in the 'American Geologist' in 1889, this was the first purpose-made Petrological microscope made in the U.S.A. produced in 1880. It is nearly identical to number 138, except for the nosepiece and other fittings to allow petrographic work. | ------- | |
143 | c 1880-1882 | NEW BIOLOGICAL OR BIOLOGICAL NO 1. | There is no round plate between the bottom of the pillar and the top of the asymmetrical foot. The two tailpieces are zig-zag in shape. The condenser fitting is manually moved up or down. The slide holder is made of brass. | Ebay Internet auction, December 2011. | |
144 | c 1880-1882 | NEW BIOLOGICAL OR BIOLOGICAL NO 1. | N/A | Has a horizontally oriented mechanical stage. There is no round plate under the asymmetrical foot. The two tailpieces are zig-zag in shape. The condenser fitting is manually moved up or down. | Ebay Internet auction, 2004. |
149 | c 1880-1882 | CONGRESS | Note the third version of the Bulloch Mechanical stage with concentric vertical controls projecting upward from the top of the stage, allowing full stage rotation. The image is from an engraving, the actual stand is in a private collection. The signature on the actual stand is slightly different than the signature on the engraving. | Private Collection | |
158 | c 1880-1882 | CONGRESS | Note the third version of the Bulloch Mechanical stage with concentric vertical controls projecting upward from the top of the stage, allowing full stage rotation. It is said to be signed: 'W.H. Bulloch, Chicago, Pat'd 1879, 158' | The Billings Collection | |
177 | c 1881-1883 | PROFESSIONAL (2 PILLAR) | This binocular microscope had two zig-zag shaped tailpieces, and the second version of mechanical stage. The equiaxed foot has a circular plate but without calibrations. | Private Collection | |
186 | c 1882-1883 | NEW BIOLOGICAL (LATER CALLED THE BIOLOGICAL NO 1.) | This microscope had two zig-zag shaped tailpieces, and the glide stage with a single pressure point, although the stage glass and slide holder are missing. The equiaxed foot has no circular plate at the place where the pillar meets the foot. This microscope has the signature of 'Pat'd 1879, W.H. Bulloch, Chicago, Ill' on the top surface of the foot, but the serial number of 186 is stamped on the underside of foot. This model could be supplied with a 'Clip Stage', mechanical stage, or 'Sliding Object Carrier' Stage; it could also be supplied with Gillett diaphragm, graduations to the substage and mirror bars, and even as a Binocular model for extra cost. | ars machina.com collection (Collection of Tom Grill) | |
200 | c 1882-1884 | BIOLOGICAL NO. 2 | This microscope lacks the round plate under the pillar and has the older asymmetrical foot. It does have the newer straight double swinging tailpieces, but not the improved condenser assembly seen starting with serial number 201; this example has the older simple substage condenser assembly. | Private collection | |
201 (earlier model) | c 1891. | BIOLOGICAL NO. 2 | N/A | This instrument has a similar but NOT identical signature to the other number 201. It is signed: 'E. B. Meyrowitz, MAKER, NEW YORK, Bulloch's Patent, 1880' with the E. B. Meyrowitz in script. The number 201 is engraved on the edge of the same toe as the signature. The number includes a 'script' type of numeral instead of a block letter type of 2, as is found on the microscope which is the next entry. | Private Collection |
201 (later) | c 1891 | BIOLOGICAL NO. 2 | Note the third version of the Bulloch Mechanical stage with concentric horizontal controls projecting from the top of the stage. Also note the improved substage, designed specifically for the Biological No. 2, and noted for the first time in the Journal of the RMS, in 1884, Vol V4, part 1, sect2,page 279. The substage was later changed by Meyrowitz who added the rack and pinion offset to the iris. This is seen on other examples of the same microscope, as in serial number 211 listed below. More interesting is the use of spiral or diagonal rack and pinion coarse focusing, a feature invented by Swift after 1890. Note that there is another microscope with the serial number 201, also with Meyrowitz signature, though the signature is slightly different. Differences include the 'script' for the older 201, vs block numbers for the later version. Also the words 'Bulloch's Patent' appear to be stamped, as opposed to actually engraved, albeit in a similar font, on the older 201. In addition, the patent date on the older example is incorrectly listed as 1880, whereas the newer example has the correct date of 1879. | This Collection | |
204 | c 1891. | BIOLOGICAL NO. 2 | Note the nickel-plated brass gliding slide carrier and an extra knob at the top of the optical tube which clamps the drawtube in position. This instrument has the same advanced substage and also has spiral (diagonal) rack and pinions for coarse focus and the substage focus as the late 201 above. | Private Collection | |
205(earlier model) | c 1891. | PROFESSIONAL | Signed: 'W.H. Bulloch, Chicago, PAT'D 1879' | This binocular microscope, made by Bulloch himself, has a serial number identical to one sold by Meyrowitz after Bulloch's death, though they are different models (see next entry). Note the second version of Bulloch's mechanical stage. | |
205 (newer) | c 1891. | ? BIOLOGICAL NO. 2 ? | Signed: 'E. B. Meyrowitz, maker, New York, Bulloch's patent 1879, no. 205' | This microscope was part of Eli Buk's collection and sold at auction (lot #713) upon his death in 2013. This is one of the instruments sold by Meyrowitz after Bulloch's death and has the same serial number as the entry immediately before this one, but was sold much later. | |
206 | c 1891. | HISTOLOGICAL | Signed: 'PAT'D 1879,W.H. Bulloch, Chicago, Ill.' | This monocular microscope, was made by Bulloch himself. Note the optional glide stage. | |
211 | c 1891 | BIOLOGICAL NO. 2 | For an almost identical microscope see number 201 above. | This microscope is virtually identical to number 201, except the stage has been replaced by a pear-shaped platform and a Bausch & Lomb accessory stage. There is an associated eyepiece micrometer (maker unclear), and a vertical illuminator (not by Bulloch). The substage assembly, modified by 'Meyrowitz,' is exactly the same as in number 201. Another addition is a clamping lever at the trunnion joint to more securely fix the inclination at a chosen angle. | Dittrick Museum of Medical History of Case-Western Reserve University(Cleveland, OH) |
221 | c. 1882-3 | PROFESSIONAL (2 PILLAR) | This binocular microscope is an example of the later 2-Pillar Professional Model | Private collection | |
242 | c 1882-1884 | HISTOLOGICAL | This microscope has a glide stage, and a nickel-plated substage ring and condenser. It bears the 1879 patent date. | Collection of Robert Marks | |
248 | c 1882-1884 | ? BIOLOGICAL NO. 2 | This microscope is very incomplete, lacking part of substage and the stage. This is likely a Biological No. 2. | sold at auction in July 1997 | |
251 | c 1883-1885 | CONGRESS | Note the THIRD version of the Bulloch mechanical stage with concentric vertically projecting controls, allowing full rotation of the stage. | Golub Collection, U.C. Berkeley | |
260 | c 1883-1885 | PROFESSIONAL (2-PILLAR) | This restored Bulloch professional features dual pillars and the second version of mechanical stage with horizontal concentric controls. | Wissner Collection | |
262 | c 1883-1885 | CONGRESS | Note the THIRD version of the Bulloch Mechanical stage with concentric vertically projecting concentric controls, allowing full rotation of the stage. | This collection | |
268 | c 1883-1885 | HISTOLOGICAL | This microscope was misidentified on Ebay as a Professional. It is a Histological as it has only one swinging tailpiece with sliding fittings, not driven by rack and pinion. It had a glass surfaced glide stage with sliding carrier. The unusual signature on top of the foot includes the Patent date of 1879 in larger block letters than the signature of W.H. Bulloch Chicago. Also we note the serial number on the bottom (underside) of the foot in this microscope. | Ebay Internet auction, 2008. | |
282 | c 1883-1885 | BIOLOGICAL NO. 2 | Note the SECOND version of the Bulloch Mechanical stage with concentric horizontally projecting concentric controls, limiting the rotation of the stage. This microscope has been referred to by some as a Professional No. 2, but this is actually incorrect. The only difference between the Professional No. 2 and the Biological No. 2, is the length of the limb where it meets the optical tube and the length of that tube. They are otherwise identical. The Biological No. 2 had a tube length of 5-6 inches, whereas the Professional No.2 had a tube length of 8-8.5 inches (excluding draw tube). This microscope has the shorter tube length. An unusual feature of this microscope is that the fine focus knob is much larger than the fine focus of most other Bulloch microscopes. The patent date is engraved above the signature on the foot, however the serial number is on the underside of the foot. | Private Collection | |
NONE | c 1885 | 'NEW STUDENT' | This microscope has the earlier zig-zag tailpiece, and was featured in an ad as well as a book of 1885. This microscope has no serial number on it at all. | This Collection | |
301 | c 1891 or later | 'PROFESSIONAL' (2 PILLAR) | This microscope has the later straight tailpieces, and the third version of mechanical stage. The equiaxed foot has a circular plate but with calibrations. This is a monocular scope. Signed: 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880' This microscope also has a diagonal rack and pinion, which means it is a later model, likely made after Bulloch's death. Another distinguishing feature of this particular microscope is the lack of the angular support plate from the limb to the stage. | Private Collection | |
302 | c 1884 | 'PROFESSIONAL No 2' | This microscope has the later straight tailpieces, and the third version of mechanical stage. The equiaxed foot has a circular plate but with calibrations. This is a monocular
scope. Signed: W.H. BULLOCH, CHICAGO ILL. This microscope also has a diagonal rack and pinion, which means it is a later model, likely made after Bulloch's death. Another distinguishing feature of this particular microscope is the lack of the angular support plate from the limb to the stage. |
Private Collection | |
308 | c 1885-1888 | PROFESSIONAL NO.2 (1 PILLAR) | This microscope has the later straight tailpieces, and the rotating glide stage. The equiaxed foot has a circular plate but without calibrations. It has the newer improved substage condenser assembly that swings out of the optical axis, and was first developed for the Biological No.2 about 1884. This is a monocular microscope. | Billings Collection | |
323 | after 1883 | Biological #2 | This microscope has the z-shaped tailpieces, and the first version of Bulloch's mechanical stage. The equiaxed foot has a circular plate but without calibrations. It has the newer improved substage condenser assembly that swings out of the optical axis, and was first developed for the Biological No.2 about 1884. This is a monocular microscope and is unsigned except for the 1879 patent date and the serial number of 323 on the bottom of the foot. The Professional #2 and the Biological #2 were virtually identical except for the length of the main optical tube. | Private Collection | |
327 | c 1880's-1891 perhaps before 1885 | HISTOLOGICAL | Note the Brass Gliding stage with single pressure point. Slide holder width 3 inches. | Private Collection | |
328 | c. 1884 | CONGRESS (FINAL FORM) | Note that the tailpieces are both flat and straight. Also note that Bulloch had now added rack and pinion adjustment to the mirror. Also note that despite its higher serial number, this instrument has straight racks and pinions. | This microscope currently resides in the Brooks Collection | |
339 | c. 1885 | 'New Biological' or 'BIOLOGICAL No. 1' |
Signed on the top of the foot: 'W.H. bulloch, Chicago, ILL' and on the underside of the foot: 'Pat'd 1879, 339' | Private Collection | |
351 | c.1885 | 'Student' | Signed on the top of the stage: 'W.H. bulloch, Chicago, ILL' and on the underside of the stage: '351' | Private Collection | |
374 | c. 1886 | PROFESSIONAL #2 | This microscope is the Professional Number 2 model with Binocular tubes. This model is identical to the Bulloch Biological Number 2 except for a longer optical tube. | Private Collection | |
381 | c. 1886 | CONGRESS (?) | N/A | This microscope is part of the Billings Collection, but not pictured in the catalog. It is said to be a duplicate of their much earlier Congress stand number 158, which is shown in the catalog and in this table above. This is very unlikely to be an exact duplicate because of the much later serial number. It is said to be signed: 'W.H. Bulloch, Chicago, Pat'd 1879' Unless the serial number is incorrect, this stand is more likely similar to number328 | Billings Collection |
383 | c. 1886 | PROFESSIONAL LITHOLOGICAL | This is a double pillar stand with all the features of the first Bulloch Lithological No. 139 above, but with the addition of straight tailpieces and a very complicated mechanical stage. Interestingly it did not have rack and pinion adjustment to the mirror. | The American Geologist of 1889, and in Bulloch's catalog of 1890. | |
392 | c. 1886 | BIOLOGICAL NO. 2 | N/A | Note that the tailpieces are both flat and straight. This microscope, a monocular is equipped with a glide stage attachment, but with only a single pressure point. The new form of substage condenser assembly was provided. The foot is asymmetrical on this example. This instrument was lacking its stage plate when sold as well as he centering knobs for the substage. It has an unusual signature with the serial number and patent date stamped on the underside of the foot, whereas on the top it is engraved in curving block letters: 'W.H. Bulloch, Chicago, Ill. | Ebay Internet auction, 2014. |
406 | c. 1886 | TRANSITIONAL STUDENT | There is only one flat and straight swinging tailpiece. Also note that the signature is on the top of the stage, and serial number is on the underside of the stage. | This microscope was sold on Ebay, and the seller was kind enough to allow me to use his images here on my website; it now resides in the Brooks Collection. | |
412 | c. 1886 | Professional No 2. | This is a Bulloch Professional No.2 with the longer tube length, which is the only feature differentiating it from a Biological No. 2. This is example is signed 'W.H.Bulloch, Chicago' on top of the foot with the patent date and the serial number on the underside of the foot. This example has with it two stages, the mechanical stage and the gliding stage, as well as some additional accesories. The provision of both stages is also noted for an example of the earlier model known as the 'Professional' as is shown on this web site. | Private collection | |
426 | c. 1887 | STUDENT TYPE (?) | ? | It is signed: 'W.H. Bulloch, Chicago' | Private Collection Collection |
443 | c. 1887 | BIOLOGICAL No 2 | It is signed: 'W.H. BULLOCH, CHICAGO, ILL' | Private Collection Collection | |
447 | c. 1887 | TRANSITIONAL STUDENT | N/A | This is apparently another example of the same microscope model as number 406. | This microscope was sold at auction on December 14, 1989 in Timonium, Maryland by Richard Opfer. |
464 | c. 1887m | PROFESSIONAL NO. 2 | This microscope has a longer optical tube typical than the Biological No. 2. | This microscope was offered for sale by Saul Moskowitz of Historical Technology in 1979. | |
468b | c. 1888 | BIOLOGICAL | Note the rotating stage set up for a slide holder | Now residing in Brooks collection | |
512 | c. 1888-1889 | BIOLOGICAL | N/A | This microscope bears both the Meyrowitz and Bulloch signatures | Private collection |
513 | c. 1888-9 | STUDENT (TRANSITIONAL OR 3RD VERSION) | This microscope bears both the Meyrowitz and Bulloch signatures | Private collection | |
551 | c. 1888-9 | 'BIOLOGICAL NO. 2' | N/A | Private collection | |
567 | c. 1888 | HISTOLOGICAL NO. 2 | Iron black foot | Private collection | |
643 | c. 1888-1890 | BIOLOGICAL NO. 2 | --- | Signed on the foot: 'MEYROWITZ BROTHERS, NEW YORK' and below that: 'W.H. BULLOCH, CHICAGO' and on the bottom of the foot: '643, PATD. 1879' otherwise nearly identical to No 201 in this collection. | Private collection |
675 | c. late 1891 (Bulloch died in November) |
CONGRESS (FINAL FORM) | The tailpieces are both flat and straight. and there is rack and pinion adjustment to the mirror. | This microscope was formerly part of the Elli Buk collection, and sold at auction (lot #702) on his death. It is the latest known serial number I have a record of. |
